50b2a4f19bSupport for block sizes greater than the page size depends on large folios, which in turn require CONFIG_TRANSPARENT_HUGEPAGE to be enabled. Because the code is wrapped in multiple layers of abstraction, this dependency is rather obscure, so users may not realize it and may be unsure how to enable LBS. As suggested by Theodore, I have added hint messages in sb_set_blocksize so that users can distinguish whether a mount failure with block size larger than page size is due to lack of filesystem support or the absence of CONFIG_TRANSPARENT_HUGEPAGE.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
